Cover
areas where potential pollutants are stored.Store pollutants such as trash, grease, paints, chemicals,
and metals to minimize contact with stormwater or water from other sources.
Keep these materials covered, labeled, and stored in appropriate containers.

Seal leaking
storage containers and dumpsters.Prevent substances like grease, liquids, and food products from
coming into contact with rainfall and entering the storm drains. Contact
local scavenger company for replacement of leaking dumpsters.

Prevent
spills and leaks. Clean up promptly when they occur. Maintain a regular inspection and repair schedule for vehicles and
equipment. Clean any spill promptly, not allowing them to evaporate. Clean
spills without water whenever possible. Rags, damp mops, and dry absorbent
materials are recommended for cleanup. Dispose of any spill waste properly.

Maintain landscaping properly.Pick up and properly dispose of trimmings and clippings, don't sweep
or blow wastes into the gutter or storm drain inlet. Avoid over-irrigation
and over-application of herbicides and pesticides that could be toxic to
wildlife in local creeks and wetlands.

Wash
vehicles and equipment in designated areas only. Wash areas must be paved and fitted to drain only to sanitary sewers.
A permit may be required to connect and discharge to the sanitary sewer.
A commercial car wash may be an alternative if your facility is not properly
equipped.

Label and inspect storm
drain inlets.Stenciling storm drain inlets on your property alerts employees and
customers that no dumping is allowed. Prevent accumulated pollutants from
washing down storm drains on your property by inspecting drains monthly,
or more often as needed, and removing and properly disposing of any debris.
